Atom has been named to the Inc. 5000 for the fifth time. It’s Inc.’s annual ranking of the fastest-growing private companies in America.

This year we ranked #1,313 nationally, up from #3,274 last year. #49 in Illinois, #70 in Business Services. Five appearances puts us on Inc.’s Honor Roll.

What five actually means

The Inc. 5000 ranks companies on three-year revenue growth. That’s the whole formula.

Each list covers a different three-year window. Making it once means you had a strong run. Making it five times means that every time the window moved forward, we were still growing, and growing off a larger base than before. The math gets less forgiving as the denominator grows.
